To see the approximate amount of available flash memory on the BlackBerry smartphone, complete the following steps.

On the Home screen, open Options.
Select Status.

The File Free field shows the approximate amount of available flash memory available for data. If you want to make sure that this value is as accurate as possible, restart the BlackBerry smartphone to initiate a full garbage collection.
The File Total field shows the amount of available flash memory after loading the wireless transceiver, operating system, and basic applications.

To see the approximate amount of occupied flash memory on the BlackBerry smartphone, complete the following steps.

What is considered low flash memory?
The BlackBerry smartphone's Java® operating system has a complex and dynamic way of determining exactly how much available flash memory it should have before starting the Low Memory Manager application. To determine if it has low flash memory, the BlackBerry smartphone takes into account a number of factors, such as the BlackBerry smartphone hardware model, the operating system version, the number of installed applications, the frequency at which BlackBerry smartphone user data is added and removed, and so on. Generally speaking, the more the BlackBerry smartphone is used, the more memory the operating system sets aside for normal, efficient operation.

Note: When the BlackBerry smartphone has determined that is has low flash memory, it automatically starts the Low Memory Manager application, which reclaims memory.

The File Free field shows 0
When the File Free field shows 0, it most likely means that the BlackBerry smartphone is full of data. The BlackBerry smartphone determines that it has low flash memory and performs more extensive garbage collections in order to make room for any new data. However, even when the BlackBerry smartphone is full of data, it is designed to operate properly. The Low Memory Manager application starts recovering flash memory when data is added that requires additional flash memory.
How the Low Memory Manager application works
The Low Memory Manager application works to recover flash memory by removing old and unimportant data; when the Low Memory Manager application is running, it does not affect the regular operation of the BlackBerry smartphone, so you are not aware that it is running. The Low Memory Manager application makes requests to all applications on the BlackBerry smartphone to recover memory. However, third-party applications must be specifically designed to interact with the Low Memory Manager application.
The Low Memory Manager application makes requests of the applications on the BlackBerry smartphone in the following order:

The Low Memory Manager application first asks all applications to remove low priority data (for example, transitory data such as browser caches). If step 1 does not recover enough free flash memory for normal operation, the Low Memory Manager application asks the applications to remove medium priority data (for example, very old messages, cached map data, and out-of-date calendar entries).
If step 1 and 2 do not recover enough flash memory, the Low Memory Manager application prompts the Messages application to remove email messages starting with those that are the least frequently accessed.
